The action is vital to success in combat or critical to preserving life. It usually involves fire or maneuver. The drill is initiated on a cue, such as an enemy action or a leaders brief order, and is a trained response to the given stimulus.

l crew drill. A critical collective action (or task) performed by a crew of a weapon or piece of equipment to use the weapon or equipment successfully in combat or to preserve life, initiated on cue, accomplished with minimal leader orders, and performed to standard throughout like units in the Army. This action is a trained response to a given stimulus, such as an enemy action, a leaders brief order, or the status of the weapon or equipment.

drill and practice. Ungraded verifications of comprehension of enabling objectives (e.g., questions, exercises, and problems). A method of instruction characterized by systematic repetition of concepts, examples, and practice problems. An ungraded practice quiz.
